Cov khoom xyaw tseem ceeb ntawm cov nplej straw yog cellulose, semi-cellulose, lignin, polyfrin, protein thiab minerals. Ntawm lawv, cov ntsiab lus ntawm cellulose, semi-cellulose, thiab lignin yog siab li 35% mus rau 40%. Cov khoom xyaw zoo yog cellulose thiab semi-cellulose.

Thawj kauj ruam hauv kev tsim cov tais diav yog tsim kua muag thiab knead lub straw. Siv ib txoj siv conveyor xa cov nplej nplej rau hauv lub tshuab ua kua muag kua muag. Tom qab lub tshuab kho, cov quav cab yuav dhau los ua 3 mus rau 5 cm ntev, mos zoo nkauj. Muab 800 kilograms ntawm dej rau 1,000 kg ntawm straw rau cov dej ntub dej, thiab tom qab ntawd sib sau ua ke rau 48 mus rau 50 teev kom txog rau thaum cov quav nyab tag nrho ntub thiab softened, thiab koj tuaj yeem nkag mus rau hauv cov txheej txheem qis dua.

Cov nplej straw softened yuav raug ntxuav thiab sib cais nyob rau hauv hydraulic nyom tshuab. Thaum cov quav cab nkag mus rau hauv lub tshuab nyom hydraulic, cov dej ntws tau ntxiv rau tib lub sijhawm los tswj cov dej khib nyiab sib xyaw ua kua rau li 10%. Tom qab kev kho mob, cov xuab zeb, nplooj, spikes, thiab nyom festivals hauv straws yog tawm nrog dej tom qab tawg. Cov khoom hnyav xws li pob zeb thiab cov hlau thaiv yog tawm los ntawm cov raj pob zeb ib puag ncig raws li qhov kev txiav txim ntawm lub zog centrifugal. Thaum kawg, qhov seem yog huv si. Ceg tawg tawg.

Lyrin yog cov khoom tseem ceeb uas muaj nyob hauv cytoplasm txheej. Nws ua rau cov hlwb lo rau ib leeg thiab ruaj khov. Yuav kom tau txais cov cellulose thiab semi-cellulose haum rau tableware, nws yog ib qho tsim nyog yuav tsum tau cais nws ntawm lignin, tshem tawm lignin los yog tshem tawm los yog tshem tawm los yog tshem tawm. Txiav cov pos hniav nrog ntoo zoo. Raws li lub hauv paus ntsiab lus ntawm degeneration ntawm qhov kub thiab txias, straw tuaj yeem muab cais ua fibers nrog kev pab ntawm straw decomposition tshuab. Thaum lub sij hawm kho ntawm 120 ° C mus rau 140 ° C, lignin hloov los ntawm crispy iav xeev mus rau ib tug heev mos roj hmab xeev, uas yog zoo sib xws nrog cellulose thiab semi-cellulose. Aggregation zog ntawm tableware.

Tom qab decomposer ntawm straw, sib tov ntawm straw dej yog xa mus rau lub tshuab ntxhua khaub ncaws kom huv si thiab concentration, tsuas yog cellulose, semic cellulose thiab transgender lignin. Tom qab ntxuav lub slurry, nws yog ib qho tsim nyog yuav tsum tau ntxiv condense nrog lub extruder kom tau txais cov ntaub ntawv raw ntawm straw ntxhuav. Txawm hais tias yav dhau los kev kho mob, tseem muaj ib qho teeb meem uas tsis tau daws, uas yog, pigment teeb meem nyob rau hauv cov nplej straw. Vim hais tias cov nplej straw nws tus kheej yog daj, xim daj yog tsau tom qab dej kub. Yuav ua li cas kom tshem tau cov xim no? Txij li thaum cov dej kub tuaj yeem tsau rau hauv cov xim, cov xim tuaj yeem raug tshem tawm los ntawm kev ua noj. Nyob rau hauv qhov kev txiav txim ntawm dej kub ntawm 96 ° C, cov xim nyob rau hauv lub fiber yog soaked tawm. Cov txheej txheem yog irreversible. Tom qab ob peb ua noj ua haus, cov straw fiber ntau slurry tuaj yeem siv los tsim cov tais diav.

Nyob rau hauv cov khoom xyaw tank, ntxiv dej nrog ib tug tag nrho hnyav ntawm 50 mus rau 60 lub sij hawm ntawm tag nrho cov nyhav ntawm straw fiber, thiab ces ntxiv 5% mus rau 8% waterproofing agent thiab 0.8% roj-pov thawj tus neeg saib xyuas raws li tag nrho cov nyhav ntawm raw khoom. , thiab do nws mus rau hauv ib tug uniform pulp rau tom qab siv. Kev noj mov ib zaug muaj ib qho tseem ceeb tshaj plaws uas yuav tsum tau ua, uas yog, cov kua zaub uas muaj txiaj ntsig zoo tsis tuaj yeem tawm, thiab cov zaub mov uas muaj roj tsis tuaj yeem xau. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov roj-pov thawj thiab cov dej tsis zoo, tab sis nws yuav tsum yog cov khoom noj khoom haus ntxiv. Cov slurry npaj tau raug thauj mus rau qhov chaw thiab molding tshuab ntawm cov khoom siv pov tseg los ntawm cov kav dej. Thaum teeb tsa, muab cov khoom noj disk pwm ua los ntawm cov hlau network ntawm lub tshuab, thiab tom qab ntawd tso lub tshuab. Tom qab cov slurry yog sib npaug zos rau hauv lub thawv, qhib lub tshuab nqus tsev twj tso kua mis hloov. Lub slurry nyob rau hauv lub thawv yuav maj mam poob. Kev qhuab ntuas. Txoj kev no tuaj yeem tshem tawm cov dej ntau dhau hauv cov slurry, kom cov khoom xyaw hauv cov slurry yog sib npaug rau sab hauv phab ntsa ntawm cov pwm. Thaum lub tshuab hluav taws xob raug tua kom tshem tawm cov hlau mesh pwm, cov ntaub ntub dej tuaj yeem raug tshem tawm. Tom qab ntawd, cov ntaub ntub dej embryo raug xa mus rau lub rooj teeb tsa lub tshuab, thiab muaj cov pwm nyob rau sab sauv thiab qis. Thaum cov pwm sab sauv thiab sab qis tau buckled ua ke, qhov cub ntawm 170 ° C mus rau 180 ° C, thiab cov dej ntsiab lus ntawm cov khoom siv rooj tog tau txog li 8% los ntawm txoj kev kub nias. Thaum lub sij hawm no, lub tableware tau pib siv.

Tom qab molding tableware, cov npoo tsis sib xws thiab cuam tshuam rau kev zoo nkauj. Yog li ntawd, nws yog tsim nyog los tsim ib tug zoo meej cutter los ntawm ib tug txheej txheem txiav. Cov pwm siv rau ntawm lub tshuab ciam teb yog tib yam li cov pwm, thiab cov pwm ntawm lub tshuab molding. Tom qab kho cov tais diav, lub tshuab tau qhib, thiab cov npoo ntau dhau ntawm lub rooj noj mov yog stamped, uas dhau los ua cov khoom siv pov tseg uas siv tau.

Ua ntej tawm hauv lub hoobkas, straw tableware yuav tsum tau kuaj xyuas, tshuaj tua kab mob thiab ntim khoom. Hauv cov txheej txheem no, qhov zoo li yuav tsum tau kuaj xyuas; Tsis tas li ntawd, txhua batch ntawm tableware yuav tsum tau ua, thiab cov sampling soj ntsuam cov ntsiab lus muaj xws li lub cev mechanical zog thiab microbial ntsuas. Txawm hais tias straw tableware muaj cov qauv tswj kev noj qab haus huv nruj hauv kev tsim khoom, kev siv tshuaj tua kab mob ozone thiab tshuaj tua kab mob ultraviolet yuav tsum tau ua ua ntej lub Hoobkas txhawm rau tua cov kab mob hauv lub cev rau ntawm lub rooj noj mov xws li spores thiab fungi.
